Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, and in particular to a spray dishwasher. BACKGROUND

[0002] With the improvement of living standards, people have higher and higher requirements for the quality of life, and thus the quality, performance, humanization of use, and intelligentization of operation of products are also increasingly required. As an excellent product, the dishwasher has gradually entered people's lives. The dishwasher is an equipment for automatically cleaning bowls, chopsticks, plates, dishes, knives, forks and other tableware, greatly facilitating people's lives.

[0003] In the process of washing or rinsing tableware in the washing cavity by the spray assembly, the related technical solution is to cover and wash the tableware by one or more spray arms installed in the washing cavity. Whether the spray arm is fixedly installed in the washing cavity or the spray arm is rotatably installed in the washing cavity, the washing coverage area of each spray arm in the washing cavity is fixed, and the coverage range of the spray area cannot be flexibly adjusted. SUMMARY

[0004] The purpose of the present application is to provide a spray dishwasher, which aims to solve the problem that the spray assembly of the dishwasher cannot flexibly adjust the coverage range of the spray area.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical solutions:

[0006] The present application provides a spray dishwasher, which comprises an inner container, a circulating pump and a spray seat. The inner container has a washing cavity. The spray seat comprises a mounting member and a spherical member, and the mounting member or the spherical member is positioned and installed in the washing cavity. The mounting member is provided with a rolling cavity and a first through hole communicating with the rolling cavity. The inner diameter of the first through hole is smaller than the outer diameter of the spherical member. The spherical member is located in the rolling cavity and is in rolling connection with the mounting member. The spherical member is provided with a first channel. The circulating pump is used to provide washing water to one end of the first channel, so that the other end of the first channel sprays washing water to different positions of the washing cavity through the first through hole.

[0007] Thus, since the spherical component is rolled within the rolling chamber, the relative position of the spherical component and the mounting component can be controlled to allow the extension direction of the first channel to have different deflection angles relative to the first straight line direction. For example, when the mounting component is positioned within the washing chamber, the rolling angle of the spherical component can be adjusted so that the end of the first channel near the first through hole can pass through the first through hole towards different positions within the washing chamber. In this way, the circulation pump can spray washing water through the first channel towards different positions within the washing chamber, facilitating flexible adjustment of the spray position and reducing dead zones in the washing chamber's dishwashing area. Thus, when the rinsing effect on the dishes is consistent, the spray base allows for precise and rapid rinsing at preset positions through flexible adjustment, reducing the rinsing and washing time of the dishwasher. Correspondingly, within the same rinsing and washing time, the spray base configuration improves the rinsing and cleaning effect on the dishes. Attached Figure Description

[0030] A dishwasher is a device that automatically cleans tableware such as bowls, chopsticks, plates, dishes, knives, and forks. Figure 1As shown, the embodiment of the present application provides a spraying dishwasher 100 (hereinafter referred to as dishwasher 100), which can include an inner container 10 and a door body 20. The inner container 10 has a washing cavity 30, in which dishes such as bowls, chopsticks, plates, dishes, knives and forks can be placed and cleaned. Among them, the inner container 10 can be provided with an opening structure communicating with the washing cavity 30, so as to facilitate the placement or removal of dishes into the washing cavity 30 through the opening structure. Taking the opening structure located at the front side of the inner container 10 as an example, the door body 20 can be arranged at the front end of the inner container 10, and the door body 20 can be rotatably connected with the inner container 10 through a hinge or a hinge structure, so that the rotating door body 20 can close or open the washing cavity 30.

[0031] When the door body 20 is in Figure 2 the opening state, it is convenient to place or remove dishes into the washing cavity 30 through the opening structure. Taking the rear side edge of the door body 20 rotatably connected with the lower side edge of the front end of the inner container 10 as an example, the door body 20 can rotate around an axis parallel to the left-right direction at this time. From left to right, when the door body 20 rotates counterclockwise so that the upper side edge of the door body 20 approaches until it fits the upper side edge of the front end of the inner container 10, the door body 20 is in a closed state at this time, which is used to close the washing cavity 30. In this way, during the cleaning of the dishes in the washing cavity 30, the door body 20 in the closed state can avoid the washing water in the washing cavity 30 from being splashed outward through the opening structure of the inner container 10. Among them, the door body 20 in the closed state can be regarded as being arranged close to the washing cavity 30 along the front-rear direction, that is, the door body 20 in the closed state is approximately perpendicular to the front-rear direction.

[0032] In addition, when installing the door body 20, the left side edge of the door body 20 can also be rotatably connected with the left side edge of the front end of the inner container 10, so that the door body 20 can rotate around an axis parallel to the up-down direction, which can also close or open the washing cavity 30. Alternatively, the opening structure of the inner container 10 can also be arranged to the left or upward, which only needs to correspondingly adjust the installation position and opening and closing mode of the door body 20.

[0033] In order to facilitate the placement and removal of dishes, as Figure 2 shown, the dishwasher 100 can also include a basket 40, which can be slidably connected with the inner container 10. Taking the inner container 10 provided with an opening structure at the front as an example, the basket 40 can slide into or out of the washing cavity 30 along the front-rear direction. Exemplarily, when installing the basket 40, rails that can slide along the front-rear direction can be installed on the left and right two inner walls of the inner container 10, and the left and right sides of the basket 40 are connected with the left and right two rails respectively, so that the basket 40 can slide out of the washing cavity 30 through the rails, so as to facilitate the placement of dishes such as bowls, chopsticks, plates, dishes, knives and forks on the basket for cleaning, or the removal of the cleaned dishes. The basket 40 can also slide into the washing cavity 30 through the rails, so as to facilitate the cleaning of the dishes in the washing cavity 30.

[0034] The inner liner 10 can contain one dish rack 40 to facilitate the placement and removal of tableware in the washing chamber 30. Alternatively, multiple dish racks 40 can be installed in the inner liner 10, such as by arranging them vertically at intervals within the washing chamber 30, allowing them to slide relative to the inner liner 10 in the front-back direction. Thus, by arranging multiple dish racks 40 within the washing chamber 30, the washing chamber 30 can be divided into multiple layers to accommodate tableware, thereby improving the space utilization of the washing chamber 30.

[0035] The dishwasher 100 can use a spray method to clean the dishes placed in the washing chamber 30. For example... Figure 3 As shown, Figure 3 This is a schematic diagram of the internal structure of a first dishwasher 100 provided in this application embodiment. The dishwasher 100 may further include a spray assembly 50, which sprays washing water to rinse the dishes in the washing chamber 30. Exemplarily, the spray assembly 50 may include a circulation pump 51, a spray arm 52, and a spray pipe 53. The spray arm 52 may be installed inside the washing chamber 30, and multiple spray holes (not shown in the figure) may be formed on the spray arm 52. The spray arm 52 can be connected to the outlet end of the circulation pump 51 via the spray pipe 53. Based on this, during the dishwashing process, driven by the circulation pump 51, washing water flows from the circulation pump 51 through the spray pipe 53 into one or more spray arms 52, and can be sprayed onto the dishes in the washing chamber 30 through the multiple spray holes on the spray arm 52 to rinse off oil stains and residues on the surface of the dishes, achieving the effect of cleaning the dishes.

[0036] The washing water sprayed from the spray nozzles will accumulate at the bottom of the washing chamber 30 after rinsing the dishes. The inlet of the circulation pump 51 can be connected to the bottom of the washing chamber 30 so that the washing water can circulate between the washing chamber 30, the circulation pump 51, the spray pipe 53, the spray arm 52 and the washing chamber 30. This can save water resources while continuously rinsing the dishes in the washing chamber 30.

[0037] It is understandable that, such as Figure 4 As shown, Figure 4 for Figure 3A cross-sectional view of a spray arm 52 is shown in FIG. 1. The spray arm 52 can include a first arm 521, a second arm 522, and a connector 523. The connector 523 can have a through-hole structure along its extension direction, the first arm 521 and the second arm 522 can be hollow structures, and one end of the first arm 521 and one end of the second arm 522 can be close to each other and connected to one end of the connector 523 to form the spray arm 52 with a spray liquid supply channel 524. That is, the through-hole structure of the connector 523, the first arm 521, and the second arm 522 are all part of the spray liquid supply channel 524. In addition, the spray arm 52 can also include a third arm, a fourth arm, or more arms, so as to increase the coverage area of the spray arm 52 in the washing cavity 30.

[0038] When the first arm 521, the second arm 522, and the connector 523 are connected and installed, the spray arm 52 can be formed by a clamping structure to form a detachable structure, which is convenient for installation and disassembly. In addition, the first arm 521, the second arm 522, and the connector 523 can be connected by a process such as gluing or hot melting to form an integral structure of the spray arm 52, so as to improve the stability of the structure of the spray arm 52. In this way, during the production of the spray arm 52, the first arm 521, the second arm 522, and the connector 523 and other parts can be separately produced, and then the above-mentioned parts are connected and installed to form the spray arm 52, which is beneficial to simplify the production process of the spray arm 52.

[0039] Continuing to refer to Figure 4 , along the extension direction of the first arm 521, a plurality of spray holes 525 can be formed on the first arm 521, and the spray holes 525 can be in communication with the spray liquid supply channel 524 in the first arm 521. Correspondingly, along the extension direction of the second arm 522, a plurality of spray holes 525 can be formed on the second arm 522, and the spray holes 525 can be in communication with the spray liquid supply channel 524 in the second arm 522. Based on this, in the washing cavity 30 shown in FIG. 1, the connector 523 can be connected with the spray pipe 53, so that the washing water can be sprayed from the spray holes 525 to the dishes placed in the washing cavity 30 through the spray liquid supply channel 524, for rinsing and cleaning the dishes. Figure 3

[0040] ​It should be noted that in the washing cavity 30, the insertion part 523 and the spray pipe 53 can be rotatably connected, so that the spray arm 52 can rotate around an axis parallel to the up-down direction under the reverse action of the sprayed washing water, so as to wash the tableware in the washing cavity 30 with a larger coverage, so as to reduce the washing dead angle of the tableware. In addition, the insertion part 523 and the spray pipe 53 can also be fixedly connected, that is, the spray arm 52 cannot rotate in the washing cavity 30, which is beneficial to improve the stability of the installation of the spray arm 52. Alternatively, the first and second arms 521 and 522 can be directly connected to one end of the same spray pipe 53, so that the washing water can be sprayed from the spray hole 525 through the spray liquid supply channel 524, without the need for an additional insertion part.

[0041] In some embodiments, referring to Figure 3 , the spray assembly 50 can further include a circulating tank 54, which can be arranged below the inner container 10 and in communication with the washing cavity 30, so that the washing water in the washing cavity 30 can accumulate in the circulating tank 54. At this time, the liquid inlet end of the circulating pump 51 can be in communication with the circulating tank 54, so that the washing water can circulate between the washing cavity 30, the circulating tank 54, the circulating pump 51, the spray pipe 53, the spray arm 52 and the washing cavity 30. When the circulating pump 51 and the circulating tank 54 are connected, the liquid inlet end of the circulating pump 51 can be connected to the circulating tank 54 through a pipeline, or the circulating pump 51 can be directly placed in the circulating tank 54, so that the washing water can cover the liquid inlet end of the circulating pump 51, both of which can drive the washing water to circulate.

[0042] Among them, as in the above embodiment, the circulating tank 54 can be a groove-shaped structure surrounded by a separate member, and the separate member can be arranged below the inner container 10 and in communication with the washing cavity 30. In addition, the circulating tank 54 can also be a part of the inner container 10, such as the bottom wall of the inner container 10 being concave from top to bottom to form a circulating tank 54 for collecting washing water, which is not limited in the present application.

[0043] If the tableware in the washing cavity 30 needs to be cleaned by the spray assembly 50, the dishwasher 100 needs to be pre-supplied with sufficient washing water, so that the washing water can circulate between the washing cavity 30, the circulating pump 51, the spray pipe 53, the spray arm 52 and the washing cavity 30. Based on this, Figure 3As shown, the spraying assembly 50 can further include a liquid inlet pipe 55 and a liquid supplement valve 56. For example, the liquid supplement valve 56 is a two-position three-way electrically controlled valve with three ports. One end of the liquid inlet pipe 55 can be connected to an external water supply device such as a water pipe or a water tower, and the other end of the liquid inlet pipe 55 can be connected to the first port of the liquid supplement valve 56. The second port of the liquid supplement valve 56 can be connected to the liquid inlet end of the circulating pump 51, and the third port of the liquid supplement valve 56 can be connected to the circulating tank 54. In this way, since the liquid supplement valve 56 is a two-position three-way electrically controlled valve, the liquid inlet pipe 55 can be connected to the circulating pump 51 by controlling the liquid supplement valve 56, so that the washing water can flow through the circulating pump 51, the spraying pipe 53, and the spraying arm 52 in sequence to wash the dishes in the washing cavity 30. When the washing water accumulated in the circulating tank 54 and the washing cavity 30 reaches a preset amount, the circulating tank 54 can be connected to the circulating pump 51 by controlling the liquid supplement valve 56, so that the washing water in the circulating tank 54 can be circulated in the dishwasher 100 by the driving of the circulating pump 51.

[0044] In other embodiments, when the circulating pump 51 is located in the circulating tank 54 or the liquid inlet end of the circulating pump 51 is directly connected to the circulating tank, the liquid inlet pipe 55 can be directly connected to the circulating tank 54 or the washing cavity 30 to supplement the washing water to the dishwasher 100. In order to facilitate the control of the supplement amount of the washing water, an electrically controlled valve structure, i.e., the liquid supplement valve 56, can be installed on the liquid inlet pipe 55 or between the liquid inlet pipe 55 and the circulating tank 54 (or the washing cavity 30). When the liquid supplement valve 56 is controlled to be opened, the washing water can be supplemented into the circulating tank 54 through the liquid inlet pipe 55. When the supplement amount of the washing water in the circulating tank 54 reaches a preset state, the liquid supplement valve 56 can be controlled to be closed to prevent the supplement of the washing water, which is simple in structure and easy to control.

[0045] In this embodiment, the supplement time of the washing water through the liquid inlet pipe 55 can be used to determine whether the preset amount of the washing water supplement is reached. For example, the opening time of the liquid supplement valve 56 can be controlled by a time relay, or the opening time of the liquid supplement valve 56 can be controlled by a controller and a preset program. In addition, the liquid level of the washing water in the circulating tank 54 or the washing cavity 30 can be detected to determine whether the preset amount of the washing water is reached. In this case, a liquid level sensor needs to be arranged in the circulating tank 54 or the washing cavity 30 to detect the liquid level of the washing water. This application does not limit the same.

[0046] For example, the liquid supplement valve 56 can be a two-position three-way electrically controlled valve with three ports. Figure 3As shown, the dishwasher 100 can further include a cabinet 60, and the inner tub 10 can be installed in the cabinet 60. A foaming agent or other heat insulation material can be filled between the inner tub 10 and the cabinet 60 for reducing heat exchange between the washing cavity 30 and the external environment, and air insulation can also be used. As an example, the circulating pump 51 and the circulating groove 54 can be installed in the space between the bottom wall of the inner tub 10 and the cabinet 60. At this time, the liquid inlet pipe 55 can be divided into two paths by a multi-way joint or a liquid distribution device. One path of the liquid inlet pipe 55 can pass through the bottom wall of the inner tub 10 and communicate with one of the spray arms 52 below the washing cavity 30, so that washing water can be sprayed upward by the spray arm 52 to wash the dishes in the washing cavity 30 from bottom to top. The other path of the liquid inlet pipe 55 can extend upward between the cabinet 60 and the inner tub 10, and can pass through the inner tub 10 near the upper region of the inner tub 10 and communicate with one of the spray arms 52 above the washing cavity 30, so that washing water can be sprayed downward by the spray arm 52 to wash the dishes in the washing cavity 30 from top to bottom.

[0047] In addition, as Figure 5 shown, Figure 5 for Figure 3 As shown in FIG. 6, the inner tub 10 is installed with the spray assembly 50. The spray pipe 53 can also be installed in the washing cavity 30, and one end of the spray pipe 53 can be connected and communicated with the circulating pump 51 through the bottom wall of the inner tub 10. When the spray pipe 53 is arranged, the spray pipe 53 can be first extended backward along the bottom wall of the inner tub 10, then extended upward along the back wall of the inner tub 10, and finally extended forward along the top wall of the inner tub 10 to connect and communicate with the spray arm 52 arranged at the upper region of the washing cavity 30.

[0048] As an example, as Figure 6 shown, Figure 6 for Figure 5 As shown in FIG. 7, an exploded view of the inner tub 10 and the spray assembly 50. In the washing cavity 30, when the spray arm 52 is arranged, one spray arm 52 can also be arranged at the middle region of the washing cavity 30 in the up-down direction, and the spray arm 52 can be connected and communicated with the spray pipe 53 through a branch pipe. In combination with Figure 7 , taking an example that two basket 40 are arranged in the washing cavity 30 in the up-down direction, the spray arm 52 can be arranged between the two basket 40. Among them, a plurality of spray holes 525 (such as Figure 4The spray arm 52 (as shown) can be arranged upwards to spray washing water upwards to rinse the tableware in the upper dish rack 40. Taking the example where the insertion part 523 of the spray arm 52 is connected to the spray pipe 53 from bottom to top, the spray holes 525 and the insertion part 523 are located on the same side of the spray arm 52. Alternatively, the spray holes 525 can be arranged downwards to rinse the tableware in the lower dish rack 40. Or, some of the spray holes 525 in the spray arm 52 can be arranged upwards and some downwards to rinse the tableware in both the upper and lower dish racks 40 simultaneously; this application does not limit this arrangement.

[0049] Correspondingly, within the washing chamber 30, the lowermost spray arm 52 can have upward-facing spray holes 525. In this case, the spray holes 525 and the connecting parts 523 can be located on the upper and lower sides of the spray arm 52, used to spray washing water upwards to clean the tableware in the upper dish rack 40. The uppermost spray arm 52 can have downward-facing spray holes 525. In this case, the spray holes 525 and the connecting parts 523 can be located on opposite sides of the spray arm 52, used to spray washing water downwards to clean the tableware in the lower dish rack 40. It should be noted that the number of spray arms 52 within the washing chamber can be one, two, three, or more. For example, spray arms 52 can be arranged above the dish rack 40, below the dish rack 40, or between two dish racks, as long as they can provide a good rinsing effect on the tableware in the dish rack 40. This application does not impose any limitations on this.

[0050] In some embodiments, continue to refer to Figure 6 The spray assembly 50 may further include a distributor 57, which may have a separate liquid supply port for each spray arm 52, and each liquid supply port may be connected to a spray arm 52 via a spray pipe 53 for independently controlling whether each spray arm 52 is in spraying mode. For example, as shown... Figure 8 As shown, Figure 8 This is a partial structural schematic diagram of a spray assembly 50 provided in an embodiment of this application. The inner liner 30 (e.g.) Figure 5 (As shown) Taking three spray arms 52 as an example, the distributor 57 can include three liquid supply ports for correspondingly connecting to the three spray arms 52 within the washing chamber 30. For the lowest spray arm 52 in the washing chamber 30, this spray arm 52 can be directly connected to one of the liquid supply ports via a connector. The other two spray arms 52 can be connected to the other two liquid supply ports via two spray pipes 53. Thus, a valve device can be installed within the distributor 57 to control the opening and closing status of each liquid supply port. This allows for control over whether one or more spray arms 52 are in spray mode, for cleaning the tableware in the corresponding location.

[0051] The distributor 57 and the circulating pump 51 can be separate units, which are simple in structure and easy to maintain.Figure 8 In some embodiments, the circulating pump 51 can be arranged outside the circulating tank 54, the liquid inlet of the circulating pump 51 can be in communication with the circulating tank 54, and the liquid outlet of the circulating pump 51 can be in communication with the distributor 57 for providing the circulating flow of the washing water to the three liquid supply ports. In addition, the distributor 57 and the circulating pump 51 can be integrated into one structure, which is compact, can reduce the occupied space and simplify the installation steps.

[0052] In some other embodiments, when controlling the spraying state of one or more spraying arms 52, an electrically controlled valve can also be installed on the spraying pipe 53 connected to the spraying arm 52. Taking the case where the number of spraying arms 52 is three as an example, an electrically controlled valve can be installed on the upstream pipe of each spraying arm 52 to control the connection or disconnection between the spraying arm 52 and the circulating pump 51 through the electrically controlled valve, so as to control whether one or more spraying arms 52 are in the spraying state. Based on this, only a multi-way joint needs to be provided between the plurality of spraying pipes 53 and the circulating pump 51 for flow distribution, without the need to additionally provide the distributor 57. In addition, the plurality of electrically controlled valves and the multi-way joint can also be regarded as a kind of split structure distributor, which is not limited.

[0053] It should be noted that, between the spraying arm 52 and the spraying pipe 53, taking the case where the spraying arm 52 is fixedly installed as an example, the connector can achieve the detachable connection between the spraying arm 52 and the spraying pipe 53 through the threaded installation, which is convenient for the installation or disassembly operation of the spraying arm 52, and can avoid the rotation of the spraying arm 52. In addition, when the spraying arm 52 and the spraying pipe 53 are rotatably connected, after the one end of the connector is installed with the spraying pipe 53, the plug-in part 523 can be plug-in installed with the other end of the connector, so that the plug-in part 523 can rotate relative to the connector under the driving of the washing water. In addition, the plug-in part 523 can also be rotatably connected with the first extending arm 521 and the second extending arm 522, at this time, only the other end of the plug-in part 523 needs to be connected and installed with the connector through the threaded connection, which can also achieve the rotation installation of the spraying arm 52.

[0054] In order to improve the cleaning effect of the dishwasher 100 on the tableware, the high-temperature cleaning effect can be achieved by spraying the washing water with a higher temperature, or the cleaning agent such as dishwashing liquid or dishwashing powder can be added in the washing cavity 30, which is beneficial to improve the cleaning effect of the dishwasher 100 on the tableware.

[0055] As shown in FIG. 1, Figure 9 Figure 9 ​A third internal structure of the dishwasher 100 is provided in the embodiments of the present application. The spraying assembly 50 can further include a spraying heater 58 and a spraying temperature sensor 59. The spraying heater 58 can be installed close to the circulating pump 51 for heating the washing water. For example, the spraying heater 58 can heat the washing water flowing therethrough, and the spraying heater 58 can be connected to the liquid outlet end of the circulating pump 51. For example, the spraying heater 58 can be installed between the distributor 57 (as shown in Figure 8 ) and the circulating pump 51, so that the heated washing water can be distributed by the distributor 57. Alternatively, the spraying heater 58 can be connected to the liquid inlet end of the circulating pump 51, so that the heated washing water can flow to the circulating pump 51. Alternatively, the spraying heater 58 and the circulating pump 51 can be integrated, i.e. the spraying heater 58 can be located in the circulating pump 51 and between the liquid inlet end and the liquid outlet end of the circulating pump 51, so that the circulating pump 51 can drive the washing water to flow through the spraying heater 58 and be heated. Alternatively, the spraying heater 58 can be directly placed in the bottom of the washing cavity 30 or in the circulating tank 54, so that the accumulated washing water can cover the spraying heater 58 and the washing water can be heated.

[0056] When installing the spraying temperature sensor 59, the spraying temperature sensor 59 can be installed at a position downstream of the spraying heater 58 along the flow direction of the washing water, such as between the spraying arm 52 and the spraying heater 58 or between the spraying heater 58 and the distributor 57, so that the spraying temperature sensor 59 can detect the temperature of the washing water heated by the spraying heater 58, so as to accurately control the heating temperature of the washing water. When installing the spraying temperature sensor 59, if the spraying pipe 53 has good heat conduction performance, the spraying pipe 53 between the spraying arm 52 and the spraying heater 58 can be installed in contact with the spraying temperature sensor 59, which is convenient for installation. Alternatively, the spraying temperature sensor 59 can be installed in the spraying pipe 53, so that the spraying temperature sensor 59 can directly contact the heated washing water, which has high detection accuracy.

[0057] Continuing to refer to Figure 9 , the spraying assembly 50 can further include a drainage pump 501, which can have a liquid inlet end and a liquid outlet end in communication. The liquid inlet end of the drainage pump 501 can be in communication with the bottom of the circulating tank 54, and the liquid outlet end of the drainage pump 501 can be connected to a drainage pipeline. Based on this, after the dishes in the washing cavity 30 are washed, the washed washing water in the washing cavity 30 and the circulating tank 54 can be drained by the drainage pump 501 between rinsing the dishes and drying the dishes.

[0058] During the process of washing the dishes, in order to avoid that large particles in the washing water circulating in the circulating tank 54 block the spraying holes 525 (as shown in Figure 4 ), the spraying pipe 53 can be provided with a filter 53a (as shown in Figure 9As shown, the spraying assembly 50 can further include a filter screen 502, which can be arranged in the circulating tank 54 so that the liquid inlet of the circulating pump 51 in the circulating tank 54 is arranged inside the filter screen 502. In this way, the washing water filtered by the filter screen 502 can flow into the liquid inlet of the circulating pump 51, and large particles can be prevented from flowing to the spraying arm 52 from the circulating pump 51 to block the spraying holes 525.

[0059] It should be noted that, during the process of washing the tableware, since large particles such as residual food are attached to the tableware, the liquid inlet of the circulating pump 51 in the circulating tank 54 can be arranged outside the filter screen 502 so that the large particles can be mixed in the washing water and discharged together under the driving of the circulating pump 51.

[0060] The working principle of the dishwasher 100 is as follows: the circulating pump 51 in the dishwasher 100 can spray the washing water at the tableware to be washed at high speed through the spraying arm 52, and the washing water can be discharged after multiple pre-washing of the tableware. Then the circulating pump 51 can wash the tableware through the washing water mixed with the detergent or the washing water with a higher temperature, and the washing water can be discharged after multiple washing of the tableware. Then the tableware can be rinsed one or more times through the washing water without mixing with the detergent. Subsequently, the tableware washed clean in the washing cavity 30 can be subjected to a drying operation.

[0061] Based on this, during the process of washing or rinsing the tableware in the washing cavity 30 through the spraying assembly 50, the tableware is covered and washed by one or more spraying arms 52 installed in the washing cavity 30 in the related technical solutions. Whether the spraying arm 52 is fixedly installed in the washing cavity 30 or the spraying arm 52 is rotatably installed in the washing cavity 30, the washing coverage area of each spraying arm 52 in the washing cavity 30 is fixed. Only the spraying arm 52 rotatably installed has a larger coverage area than the spraying arm 52 fixedly installed. However, the coverage range of the spraying arm 52 rotatably installed is still fixed, and the coverage range of the spraying area cannot be flexibly adjusted.

[0062] To solve the above problems, the dishwasher 100 can further include a spraying seat 70, which can be installed in the washing cavity 30. Figure 9 As shown in Figure 10 , Figure 10 As shown in Figure 9 , the spraying seat 70 can include a mounting member 71 and a spherical member 72. As shown in Figure 11 , Figure 11 As shown in Figure 10A sectional view of the spray seat 70 is shown. The mounting member 71 can be provided with a rolling cavity 711 and a first through hole 712 and a second through hole 713 communicating with the rolling cavity 711. The first through hole 712 and the second through hole 713 can be formed at opposite ends of the rolling cavity 711 along a first linear direction (i.e. the X direction). The inner diameter of the first through hole 712 and the second through hole 713 can be smaller than the outer diameter of the spherical member 72, and the inner diameter of the rolling cavity 711 can be larger than the outer diameter of the spherical member 72, so that the spherical member 72 can be located in the rolling cavity 711 and rolling connected with the mounting member 71. Since the spherical member 72 can be provided with a first channel 721, the spherical member 72 can roll relative to the mounting member 71 in the rolling cavity 711, so that the first channel 721 can have different position states relative to the first through hole 712.

[0063] Based on this, the mounting member 71 can be connected and mounted with the inner container 10, that is, the mounting member 71 can be positioned and mounted in the washing cavity 30. The end face of the mounting member 71 provided with the second through hole 713 can be in contact and connection with the bottom wall of the inner container 10, and the circulating pump 51 can be connected and conducted through the spray pipe 53 and the second through hole 713, so that the circulating pump 51 can provide washing water to one end of the first channel 721 through the second through hole 713 and the rolling cavity 711. In this way, through the transmission of the first channel 721 in the spherical member 72, the washing water can be sprayed from the other end of the first channel 721 and through the first through hole 712 to different positions of the washing cavity 30, for washing dishes in the washing cavity 30 through different angles.

[0064] In this way, since the spherical member 72 is rolling mounted in the rolling cavity 711, the relative position state of the spherical member 71 and the mounting member 71 can be controlled to make the extension direction of the first channel 721 have different deflection angles relative to the first linear direction. For example, when the mounting member 71 is positioned and mounted in the washing cavity 30, the rolling angle of the spherical member 72 can be adjusted so that one end of the first channel 721 close to the first through hole 712 can be directed through the first through hole 712 to different positions of the washing cavity 30. In this way, the circulating pump 51 can spray washing water through the first channel 721 to different positions of the washing cavity 30, which is convenient for flexible adjustment of the spraying position and is beneficial to reduce the dead angle of the dishes in the washing cavity 30. In this way, when the washing effect of the dishes is consistent, through the setting of the spray seat 70, the preset position can be accurately and quickly washed through flexible adjustment, which is beneficial to reduce the time of the washing and rinsing process of the dishwasher 100. Correspondingly, within the same washing and rinsing time, the setting of the spray seat 70 is beneficial to improve the washing and cleaning effect of the dishes.

[0065] It should be noted that for the spray seat 70, as shown in Figure 11 The rolling cavity 711 can be approximately a spherical cavity for completely accommodating the spherical member 72. Correspondingly, asFigure 12 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 12 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 9 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 12 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner.

[0066] as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 12 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 13 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 9 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner.

[0067] as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 12 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 13 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner. Figure 9 as shown in FIG. 7B, the spray seat 70 can be installed on the inner container 10, and the spray seat 70 can be connected with the inner container 10 in a position-locked manner.

[0068] Furthermore, in the above embodiments, the mounting member 71 can also be positioned and installed on the bottom wall of the inner tank 10 near the side wall. Alternatively, the mounting member 71 and the inner tank 10 can be connected by a bracket. Without affecting the rotation of the spherical member 72 within the rolling chamber 711, the circulation pump 51 can be connected to the end of the first channel 721 away from the nozzle 73 via the spray pipe 53. Thus, after the circulation pump 51 is turned on, the deflection angle of the spherical member 72 relative to the mounting member 71 can be adjusted so that washing water can be sprayed from the end of the first channel 721 near the first through hole 712, the nozzle 73, or the first through hole 712 to different locations on the tableware.

[0069] like Figure 14 As shown, the spray base 70 may further include a positioning bracket 74. The positioning bracket 74 may include a first connecting ring 741, a second connecting ring 742, and a plurality of support rods 743. The first connecting ring 741 and the second connecting ring 742 can be installed at intervals between each other via the plurality of support rods 743, so that the plane containing the first connecting ring 741 and the plane containing the second connecting ring 742 can be arranged at intervals. Based on this, the spray base 70 with the hemispherical structure of the rolling cavity 711 can be positioned and installed as follows: Figure 13 Taking the spray seat 70 shown as an example, in Figure 9 Within the washing chamber 30 shown, the second connecting ring 742 can be fixedly connected to one side wall of the inner tank, and the end of the spherical member 72 away from the first through hole 712 along the Y direction can be connected to the first connecting ring 741. Alternatively, the end of the first channel 721 away from the first through hole 712 can be arranged within the first connecting ring 741 to facilitate connection of the circulation pump 51. In this case, the inner diameter of the first connecting ring 741 can be slightly larger than the inner diameter of the first channel 721 to avoid the larger size of the first connecting ring 741 obstructing the deflection angle between the mounting member 71 and the spherical member 72.

[0070] Alternatively, the size of the first connecting ring 741 can be increased so that it can contact the end of the connecting mounting member 71 away from the first through hole 712 in the X direction, allowing the spherical member 72 to flexibly adjust its deflection angle. Alternatively, the first connecting ring 741 can contact the mounting member 71 with a spherical rolling cavity 711. In this embodiment, the spray seat 70 can be connected and installed close to the bottom or top wall of the inner liner 10, or it can be connected and installed close to the side wall of the inner liner 10 located between the top and bottom walls. This can be flexibly adjusted according to requirements and is not limited thereto.

[0071] In some embodiments, taking the rolling cavity 711 in the mounting member 71 as an example, such as... Figure 15 As shown, Figure 15 for Figure 11FIG. 6 is a sectional view of another state of the mounting seat 70. Since the rolling cavity 711 has the first through hole 712 and the second through hole 713 sequentially communicated at opposite ends along the X direction, the circulating pump 51 (as shown in Figure 9 FIG. 6) can be connected with the second through hole 713 through the spray pipe 53, so as to facilitate flexible arrangement of the spray seat 70 in the washing cavity 30. In addition, if the mounting member 71 is positioned and mounted at the bottom wall of the inner container 10, the liquid outlet end of the circulating pump 51 can also be directly connected with the second through hole 713 through the bottom wall of the inner container 10, without the need of additionally arranging the spray pipe 53. Correspondingly, the liquid outlet end of the circulating pump 51 can also be directly connected with the Figure 13 first channel 721 shown in FIG. 6 through the inner container 10.

[0072] Continuing to refer to Figure 15 , the spherical member 72 can have a first channel 721 opened and communicated along a second straight direction (i.e., the Y direction). In the embodiment of the present application, the X direction can be a reference direction based on the mounting member 71, and the Y direction can be a reference direction based on the spherical member 72. Due to different mounting positions of the mounting seat 70 in the washing cavity 30 (as shown in Figure 9 FIG. 6), the X direction and the Y direction can be corresponding up and down, left and right, or front and rear directions in actual application. In addition, since the spherical member 72 is rolling mounted in the rolling cavity 711 of the corresponding spherical structure, the spherical member 72 (or the spray seat 70) can have an initial state and a plurality of deflection states.

[0073] For example, in combination with Figure 11 and Figure 12 , when the spherical member 72 is in the initial state, the first channel 721 can be aligned and communicated with the first through hole 712 and the second through hole 713 along the Y direction. At this time, the washing water can be sprayed to the preset position of the washing cavity 30 through the second through hole 713, the first channel 721 and the first through hole 712 in sequence, for flushing and cleaning the tableware at the position. At this time, the X direction and the Y direction can be considered as two approximately parallel directions. Alternatively, it can also be considered that the axis of the first through hole 712 (which can be considered as a straight line where the X direction is located) can be approximately co-linearly arranged with the axis of the first channel 721 (which can be considered as a straight line where the Y direction is located).

[0074] In addition, when the spherical member 72 is switched to the deflection state, in combination with Figure 15 , for example, the plane shown in the figure is a plane perpendicular to the front and rear directions. In the spray seat 70, the spherical member 72 can be deflected in any direction within a range of 360° relative to the mounting member 71, such as front and rear, left and right, left front, left rear, right front or right rear, i.e., the plurality of deflection states of the spherical member 72 can correspond to a plurality of different Y directions. So that the deflection angle between the spherical member 72 and the mounting member 71, i.e., the included angle between the X direction and the Y direction, can be greater than 0°, so that the washing water sprayed by the spray seat 79 can be sprayed to the washing cavity 30 (as shown inFigure 9 As shown, the plurality of deflection states of the spray seat 70 can be different deflection angles of the mounting member 71 relative to the spherical member 72 in different directions.

[0075] Correspondingly, in the embodiment shown, the plurality of deflection states of the spray seat 70 can be different deflection angles of the mounting member 71 relative to the spherical member 72 in different directions. Figure 13 In the embodiment shown, the plurality of deflection states of the spray seat 70 can be different deflection angles of the mounting member 71 relative to the spherical member 72 in different directions.

[0076] It should be noted that for the deflection angle between the mounting member 71 and the spherical member 72, the deflection angle a can be in the range of 0° < a ≤ 45°. In addition, according to needs, the deflection angle can also be set to a maximum of about 50°. Among them, the deflection angle of the deflection state can be flexibly selected between 0° and 45°, such as in the same deflection direction, a deflection state can be set every 0.5°, 1°, 2°, 3°, 4° or 5°, and the deflection interval angle of the spray seat 70 can be flexibly adjusted according to actual needs, which is not limited.

[0077] For the structure of the nozzle 73, the nozzle 73 can be detachably connected with the corresponding mounting member 71 or the corresponding spherical member 72, so as to facilitate flexible adjustment of the size of the washing water injection port. Among them, the nozzle 73 can be located on the side of the mounting member 71 close to the first through hole 712 in the X direction. For example, Figure 13 For example, as shown in the nozzle 73 in the middle, when the spherical member 72 is positioned and installed, the nozzle 73 can be connected with the mounting member 71 and the first through hole 712, so that the first through hole 712 in the deflection state or the initial state can spray washing water in the X direction through the nozzle 73.

[0078] For example, as shown in the nozzle 73 in the middle, when the spherical member 72 is positioned and installed, the nozzle 73 can be connected with the mounting member 71 and the first through hole 712, so that the first through hole 712 in the deflection state or the initial state can spray washing water in the X direction through the nozzle 73. Figure 15 For example, as shown in the nozzle 73 in the middle, when the spherical member 72 is positioned and installed, the nozzle 73 can be connected with the mounting member 71 and the first through hole 712, so that the first through hole 712 in the deflection state or the initial state can spray washing water in the X direction through the nozzle 73.

[0079] In order to facilitate the control of the deflection direction and the deflection angle of the spherical member 72 or the mounting member 71 in the spray seat 70. For example, Figure 16as shown, Figure 16 as shown, Figure 11 A sectional view of the mounting seat 70 shown in FIG. 7A is shown in FIG. 7B. The shower seat 70 can further include a plurality of magnetic control elements 75 which can be spaced apart around the axis of the first through hole 712 and within the mounting member 71. The plurality of magnetic control elements 75 within the mounting member 71 can be arranged proximate to the rolling cavity 711. In combination with the magnetic positioning element 76 within the spherical member 72, the magnetic control elements 75 can be used to control the deflection direction and deflection angle of the spherical member 72. Figure 17 , Figure 17 A sectional view of the mounting seat 70 shown in FIG. 7A is shown in FIG. 7B. The shower seat 70 can further include a plurality of magnetic control elements 75 which can be spaced apart around the axis of the first through hole 712 and within the mounting member 71. The plurality of magnetic control elements 75 within the mounting member 71 can be arranged proximate to the rolling cavity 711. In combination with the magnetic positioning element 76 within the spherical member 72, the magnetic control elements 75 can be used to control the deflection direction and deflection angle of the spherical member 72. Figure 11 ,

[0080] For example, the number of magnetic positioning elements 76 can be one, and when the mounting member 72 is in the initial state, the magnetic positioning element 76 within the spherical member 72 can be arranged proximate to the center of the plurality of magnetic control elements 75, so that each energized magnetic control element 75 can have approximately equal magnetic attraction to the magnetic positioning element 76.

[0081] In addition, the number of magnetic positioning elements 76 can also be a plurality of one-to-one corresponding to the magnetic control elements 75, i.e. the plurality of magnetic positioning elements 76 within the spherical member 72 can be spaced apart around the first channel 721. When the spherical member 72 is in the initial state, one magnetic positioning element 76 can be proximate to and aligned with the magnetic control element 75 in one mounting member 71.

[0082] The number of magnetic control elements 75 can be three, four, five or even more, and the plurality of magnetic control elements 75 can be evenly distributed around the axis of the first through hole 712 on the mounting member 72. For example, in the mounting member 71, three magnetic control elements 75 can be distributed at intervals of 120°, four magnetic control elements 75 can be distributed at intervals of 90°, six magnetic control elements 75 can be distributed at intervals of 60°, eight magnetic control elements 75 can be distributed at intervals of 45°, or twelve magnetic control elements 75 can be distributed at intervals of 30°. The magnetic control element 75 can be an electromagnet, an electromagnetic coil or the like structure which can generate a magnetic field when energized, and is not limited in this regard.

[0083] In combination with the magnetic positioning element 76 within the spherical member 72, the magnetic control elements 75 can be used to control the deflection direction and deflection angle of the spherical member 72. Figure 17 In combination with the magnetic positioning element 76 within the spherical member 72, the magnetic control elements 75 can be used to control the deflection direction and deflection angle of the spherical member 72. Figure 9In the embodiment shown in FIG. 6, the spray seat 70 is provided with the magnetic positioning member 76 and the counterweight 77. The magnetic positioning member 76 is arranged in the ball 72 to adjust the center of gravity of the ball 72. The counterweight 77 is arranged in the ball 72 to adjust the center of gravity of the ball 72. The ball 72 can have an initial state and a plurality of deflection states. The initial state can be the automatic reset state of the ball 72. The ball 72 can be automatically reset to the initial state when the plurality of magnetic controllers 75 are in the power-off state. The ball 72 can be automatically reset to the initial state when the plurality of magnetic controllers 75 are in the power-off state. Figure 17 In the embodiment shown in FIG. 6, the spray seat 70 is provided with the magnetic positioning member 76 and the counterweight 77. The magnetic positioning member 76 is arranged in the ball 72 to adjust the center of gravity of the ball 72. The counterweight 77 is arranged in the ball 72 to adjust the center of gravity of the ball 72. The ball 72 can have an initial state and a plurality of deflection states. The initial state can be the automatic reset state of the ball 72. The ball 72 can be automatically reset to the initial state when the plurality of magnetic controllers 75 are in the power-off state. The ball 72 can be automatically reset to the initial state when the plurality of magnetic controllers 75 are in the power-off state.

[0084] It should be noted that, in the embodiment shown in FIG. 6, the magnetic positioning member 76 and the counterweight 77 can be the same component. For example, the ball 72 can be made of plastic, which has a relatively low density. Correspondingly, the magnetic positioning member 76 (or the counterweight 77) can be a magnetic iron block or iron sand, which is filled in the ball 72 near the one end of the second through hole 713. The magnetic positioning member 76 (or the counterweight 77) can not only lower the center of gravity of the ball 72 in the vertical direction, but also be attracted by the energized magnetic controller 75 to adjust the deflection direction and the deflection angle of the ball 72. Figure 17

[0085] In the embodiment shown in FIG. 6, the magnetic positioning member 76 (or the counterweight 77) can be filled in the corresponding position of the ball 72 by rust-proof treatment or complete sealing filling method, so that the magnetic positioning member 76 (or the counterweight 77) is prevented from contacting air or washing water, thereby improving the cleaning effect on the tableware in the washing cavity 30. Alternatively, in some embodiments, the magnetic positioning member 76 and the counterweight 77 can be two independent components filled in the corresponding position of the ball 72, which is not limited in the present application.

[0086] In the above embodiment, since the ball 72 is provided with only the first channel 721, when the deflection angle of the spray seat 70 is large, the two ends of the first channel 721 can not be aligned with the first through hole 712 and the second through hole 713 in the Y direction. Thus, the water pressure of the washing water sprayed by the spray seat 70 is affected, thereby affecting the flushing and cleaning effect on the tableware.

[0087] Based on this, continuing to refer to FIG. 6, the ball 72 can be further provided with a plurality of second channels 722. The plurality of second channels 722 can be arranged in the ball 72 to align with the first through hole 712 and the second through hole 713 in the Y direction. Figure 17 Figure 18 Figure 18 For example, the ball 72 can be made of plastic, which has a relatively low density. Correspondingly, the magnetic positioning member 76 (or the counterweight 77) can be a magnetic iron block or iron sand, which is filled in the ball 72 near the one end of the second through hole 713. The magnetic positioning member 76 (or the counterweight 77) can not only lower the center of gravity of the ball 72 in the vertical direction, but also be attracted by the energized magnetic controller 75 to adjust the deflection direction and the deflection angle of the ball 72.​​​Figure 17 A bottom view of the ball 72 shown in FIG. 6, a plurality of second channels 722 can be arranged around the axis of the first channel 721. The first ends of the plurality of second channels 722 can be arranged in communication with the first channel 721. When the ball 72 is in the initial state, the second ends of the plurality of second channels 722 can be arranged close to the side where the second through hole 713 is located, and the second ends of the plurality of second channels 722 can be arranged in spaced relation to the first channel 721. In this way, the plurality of second channels 722 in the handling state can be arranged in one-to-one correspondence with the plurality of magnetic controls 75, and when one of the magnetic controls 75 is energized to make the ball 72 in the deflected state, the second end of one of the second channels 722 can be at least partially aligned with and in communication with the second through hole 713. So that the washing water can pass through the second through hole 713, the second channel 722, the first channel 721 and be sprayed in the corresponding second linear direction to the washing cavity 30 (as shown in FIG. 6) along the first through hole. Figure 9

[0088] In this process, the current of the magnetic control 75 can be gradually increased, so that the alignment area of the second end of the second channel 722 with the second through hole 713 can first increase and then decrease, and when the alignment area of the second end of the second channel 722 with the second through hole 713 decreases to 0, the ball 72 can have a maximum deflection angle, such as 45°, 50° or other parameters, which are not limited.

[0089] In the above embodiment, the eight magnetic controls 75 can be used to control the alignment and conduction of the corresponding eight directional second channels 722 with the second through hole 713. In addition, the number of magnetic controls 75 can also be reduced, and the eight directional second channels 722 can also be controlled. It is explained that in the embodiment of the application, the force between the magnetic control 75 and the magnetic positioning member 76 can be mainly attractive force, and based on this, when the magnetic control 75 is energized to make the ball 72 deflect in one direction, the second channel 722 arranged in the opposite direction can be aligned and conducted with the second through hole 713, that is, one second channel 722 and one magnetic control 75 are arranged correspondingly.

[0090] For example, if Figure 19 ​The spherical component 72 is provided with four magnetic control elements 75 (E1, E3, E5, and E7) and four second channels 722 (W1, W3, W5, and W7). Based on this, the spherical component 72 can also be provided with multiple third channels 723. These third channels 723 can be spaced apart around the axis of the first channel 721, and the first ends of the third channels 723 can communicate with the first channel 721. When the spherical component 72 is in its initial state, the second ends of the third channels 723 can be arranged close to the second through hole 713, and the second ends of the third channels 723 are spaced apart from the first channel 721. The multiple third channels 723 can be arranged one-to-one with the multiple second channels 722, and along the distribution direction of the multiple second channels 722, a third channel 723 can be located between two adjacent second channels 722. Based on this, along the arrangement direction of the multiple magnetic control components 75, when two adjacent magnetic control components 75 (such as E1 and E3) are energized to make the spherical component 72 deflected, the second end of the corresponding third channel 723 (i.e. W2) can be at least partially aligned with and connected to the second through hole 713.

[0091] Thus, the deflection direction and angle of the four second channels 722 and the four third channels 723 can be adjusted and controlled through four magnetic control units 75, resulting in a simple structure. Furthermore, along the arrangement direction of the multiple magnetic control units 75, the interval angle between two adjacent magnetic control units 75 can be less than 180°.

[0092] In addition, multiple magnetic control units 75 can be rapidly and alternately energized to allow the spherical part 72 to swing back and forth between multiple deflection directions or deflection angles. This allows for high-frequency back-and-forth rinsing of the tableware in the corresponding area of ​​the washing chamber 30, thereby improving the rinsing speed and rinsing effect of the tableware in that area.

[0093] In some other embodiments, such as Figure 20 As shown, Figure 20 for Figure 10 The image shows a bottom view of the spherical component 72. The spherical component 72 may also have a fourth channel 724, which may be an annular structure and arranged around the first channel 721. The first end of the fourth channel 724 may communicate with the first channel 721. When the spherical component 72 is in its initial state, the second end of the fourth channel 724 may be located near the second through hole 713 (e.g., ...). Figure 17 The fourth channel 724 is disposed on one side (as shown), and the second end of the fourth channel 724 can be spaced apart from the first channel 721. The diameter of the fourth channel 724 can be gradually reduced along the second straight line direction away from the second through hole 713. When the magnetic control 75 is energized to deflect the spherical member 72, the second through hole 713 can be aligned with and connected to the second end portion of the fourth channel 724.

[0094] Thus, since the fourth channel 724 is approximately an annular structure around the first channel 721, the ball 72 in the deflected state can be deflected 360° without dead angle in a plane perpendicular to the X direction when passing through the second through hole 713 via the fourth channel 724, which is beneficial to improve the control accuracy of the spray seat 70 on the flushing area.

[0095] It should be noted that for the fourth channel 724, it can be considered as a plurality of second channels arranged continuously around the circumference of the first channel 721, and only has a spacing of 1-3 mm between adjacent two second channels for connecting and fixing the part of the ball 72 between the first channel 721 and the fourth channel 724. In addition, the fourth channel 724 is a complete annular channel, and a plurality of connecting ribs need to be arranged in the fourth channel 724 for fixing the part of the ball 72 between the fourth channel 724 and the first channel 721. This part of the ball 72 can be used to seal and fill the magnetic positioning member 76 or the counterweight 77. Good sealing performance and high structural strength need to be provided.

[0096] For example, the end of the mounting member 71 provided with the second through hole 713 is taken as an example. When the end of the mounting member 71 is in contact and connected with the bottom wall of the inner container 10, the counterweight 77 and the magnetic positioning member 76 can be an integrated member and located at the end of the ball 72 close to the second through hole 713. When the end of the mounting member 71 is in contact and connected with the top wall of the inner container 10, the counterweight 77 and the magnetic positioning member 76 can be a split type member, that is, the counterweight 77 is located at the end of the ball 72 close to the first through hole 712, and the magnetic positioning member 76 can be located at the end of the ball 72 close to the second through hole 713. In addition, the end of the mounting member 71 can also be in contact and connected with the three side walls of the inner container 10, and the counterweight 77 and the magnetic positioning member 76 can be a split type member, that is, the magnetic positioning member 76 can be located at the end of the ball 72 close to the second through hole 713, and the counterweight 77 is used to make the ball 72 in the natural state be in the initial state.

[0097] In order to facilitate the control of the dish washing machine 100 to run the flushing process and the rinsing process, etc., as shown in Figure 21 , the mounting member 71 is provided with a plurality of through holes 711, 712 and 713, and the ball 72 is arranged in the mounting member 71 and can be deflected in the mounting member 71. The ball 72 is in the natural state in the initial state, and the ball 72 is in the deflected state in the deflected state. The ball 72 is in the deflected state in the deflected state. Figure 21A circuit system architecture of a dishwasher 100 is provided in the embodiments of the present application. The dishwasher 100 can further include a controller 80, which refers to a device capable of generating operation control signals according to instruction operation codes and timing signals to instruct the dishwasher 100 to execute control instructions. Exemplarily, the controller 80 can be a central processing unit (CPU), a general processor network processor (NP), a digital signal processing (DSP), a programmable logic device (PLD), a microprocessor, a microcontroller, or any combination thereof. The controller 80 can also be other devices with processing functions, such as a circuit, a device (relay, etc.), or a software module, and the embodiments of the present application do not make any limitation in this regard.

[0098] As shown in Figure 21 , the controller 80 can be electrically connected with one or more electric elements in the spray assembly, such as the circulating pump 51, the liquid supplement valve 56, the liquid distributor 57, the spray heater 58, the spray temperature sensor 59, and the drain pump 501, to control the dishwasher 100 to execute a washing program and a rinsing program. In addition, the controller 80 can be electrically connected with a plurality of magnetic electric controls 75 to control whether the corresponding magnetic electric controls 75 are powered on or not by preset current and preset time, thereby controlling the initial state and a plurality of deflection states of the spray seat 70 (as shown in Figure 9 ).

[0099] Exemplarily, after the user selects and starts the dishwasher 100, the controller 80 can control the electric elements in the dishwasher 100 to work, so that the dishwasher 100 sequentially runs the washing program and the rinsing program to flush the tableware in the washing cavity to meet the user's needs. For example, under the user's selection, the controller 80 can be configured to:

[0100] The controller 80 can control the circulating pump 51 to be turned on and provide washing water to the spray seat 70. At this time, the spray arm 52 can be in a working state of flushing the tableware, or the spray seat 70 can be operated alone to flush the tableware in the corresponding area. In this way, whether the spray seat 70 and the corresponding spray arm 52 are in a flushing cleaning state can be controlled by the liquid distributor 57 downstream of the circulating pump 51, that is, the spray seat 70 can be connected to the liquid outlet end of the circulating pump 51 through the liquid distributor 57, or a separate circulating pump 51 can be provided for the spray seat 70 to supply washing water, and no limitation is made in this regard.

[0101] Subsequently, along the distribution direction of the plurality of magnetic electric controls 75, such as the clockwise direction or the counterclockwise direction. Each magnetic electric control 75 can be controlled to operate for a preset time in sequence with a preset current. Subsequently, the preset current can be adjusted in size, and the preset time can also be adjusted in length. Subsequently, each magnetic electric control 75 can be controlled to operate again for a preset time in sequence with the adjusted preset current.

[0102] In combination Figure 17 and Figure 19 The eight magnetic electric controls 75 distributed at intervals of 45° in the mounting member 72 can be numbered in sequence as E1, E2, E3, E4, E5, E6, E7, and E8, and the four second channels 722 and the four third channels 723 can be numbered in sequence as W1, W2, W3, W4, W5, W6, W7, and W8. Based on this, when the magnetic electric control E1 is powered on, the first channel W1 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E2 is powered on, the second channel W2 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E3 is powered on, the first channel W3 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E4 is powered on, the second channel W4 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E5 is powered on, the first channel W5 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E6 is powered on, the second channel W6 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E7 is powered on, the first channel W7 can be at least partially aligned and communicated with the second through hole 713. When the magnetic electric control E8 is powered on, the second channel W8 can be at least partially aligned and communicated with the second through hole 713.

[0103] In this way, the eight magnetic electric controls 75 of E1, E2, E3, E4, E5, E6, E7, and E8 can be sequentially controlled to be powered on for one second with a first preset current. At this time, the deflection angle of the mounting member 72 in the corresponding eight directions can be approximately 45°. Subsequently, the second preset current can be lowered, and each magnetic electric control 75 can be sequentially controlled to be powered on for one second with the second preset current. At this time, the deflection angle of the mounting member 72 in the corresponding eight directions can be approximately 30°. Then the third preset current can be lowered, and each magnetic electric control 75 can be sequentially controlled to be powered on for one second with the third preset current. At this time, the deflection angle of the mounting member 72 in the corresponding eight directions can be approximately 15°. The preset current can include the first preset current, the second preset current, and the third preset current. In order to make the coverage area of the shower seat 70 in the washing cavity 30 approximate to three sequentially decreasing annular spray areas.

[0104] In actual application, the size of the preset current and the length of the preset time can be adjusted according to the difference in the placement of the tableware in the dishwasher 100, the difference in the amount of stains, and the needs of different groups of people, so as to change the spraying area of the annular jet, and to adapt to the placement of different tableware.

[0105] It should be noted that in the above three repeatedly executed programs, the eight magnetic electrical controls 75 of E1, E2, E3, E4, E5, E6, E7, and E8 change the deflection direction of the spherical member 72 by 45° each time. After the magnetic electrical control 75 of E8 is energized for 1 second, the next magnetic electrical control 75 of E1 can be connected with a changed preset current after one to two seconds. In this process, the spherical member 72 in the initial state can vertically upward or vertically downward spray washing water along the first straight line direction. In addition, the above three sets of repeatedly executed control programs can also be run independently, and this is not limited.

[0106] In some embodiments, the controller 80 can also be configured to:

[0107] After the controller 80 controls the circulating pump 51 to be turned on and provides washing water to the spray seat 70, the preset current can be used to control each of the magnetic electrical controls 75 to be energized for a preset time in sequence, and the controller 80 can also repeatedly execute the above step on the plurality of magnetic electrical controls 75.

[0108] For example, between two spaced-apart magnetic electrical controls 75, the controller 80 can control each of the magnetic electrical controls 75 to be energized for a preset time with a preset current and alternately reciprocate. With the preset current, the spherical member 72 can be deflected by 45°, and taking the example that the two magnetic electrical controls 75 are approximately spaced apart by 180°, the spherical member 72 can reciprocate in a partial linear area in the washing cavity 30 to sweep and flush the tableware in the washing cavity 30.

[0109] In addition, in the above example, the above step can also be controlled to be repeatedly executed by three spaced-apart magnetic electrical controls 75, so that the spherical member 72 can reciprocate along a triangular trajectory in the washing cavity 30 to sweep and flush the tableware in the washing cavity 30. If the above step can be controlled to be repeatedly executed by four spaced-apart magnetic electrical controls 75, so that the spherical member 72 can reciprocate along a rectangular trajectory in the washing cavity 30 to sweep and flush the tableware in the washing cavity 30.

[0110] It should be noted that according to the needs of the user, the corresponding magnetic electrical controls 75 can also be controlled to make the washing water sprayed by the spherical member 72 aim at the tableware in the key pollution area and continuously flush, which is beneficial to reduce the overall flushing and cleaning time of the tableware.

[0111] In the embodiment of the present application, by changing the preset current size of each power supply, it can be found from the spraying coverage of the water column flow that the spraying washing in all directions of the universal coverage inside the dishwasher 100 is approximately obtained. By increasing the current oscillation power supply frequency and shortening the preset time, the operation time for completing the related working step can be further reduced, and the spraying water flow can further improve the washing coverage frequency of the related position tableware in unit time. It is beneficial to improve the cleaning degree of the dishwasher to the tableware and save the operation time of the washing and rinsing program.

[0112] In the description of the present specification, specific features, structures, materials or characteristics can be combined in any one or more embodiments or examples in a suitable manner.

[0113] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, and any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
